actionset.java

一个java权限系统.主要使用j2ee框架实现.

package com.wxd.common.popedom.domain.command;

import java.util.*;

import com.wxd.common.popedom.domain.entity.Action;
import com.wxd.common.popedom.persistence.ActionDao;

public class ActionSet {
	private  ActionDao actionDao;
	private static Map actions=null;
	

	public ActionSet(ActionDao actionDao) {
		super();
		this.actionDao = actionDao;
	}

	public ActionSet() {
	}

	private void init(boolean isInit) {
		if(actions==null || isInit){
		  actions = actionDao.getAllActionMap();
		  System.out.println("From DB fetch all actions.");
		}
	  System.out.println("From memory fetch all actions.");
	}

	public Action getAction(String actionId) {
		init(false);
		return (Action) actions.get(actionId);
	}

	public Map getAllActions() {
		init(false);
		return actions;
	}
	
	public void refresh(){
		init(true);
	}

	public ActionDao getActionDao() {
		return actionDao;
	}

	public void setActionDao(ActionDao actionDao) {
		this.actionDao = actionDao;
	}
